Plants not flowering at day 18

[Shayne010944]

I’m in day 18 of flower since I’ve switched to 12/12.

My plant in the middle is purple punch and is flowering . The other 3 are northern lights .

The northern lights will not start flowering , and I cannot see any male signs either .

Anyone know why they wouldn’t be yet and the purple punch is ?

Anyone feel free to suggest why

My guess is the fact their sativa dominat, which can take up to 12 weeks for the fulll flowering cycle. You can see the new growth from the stretch, so their doing what they should.

didn’t anyone tell you, patience is the more important growers tool?

Some plants take a long time. I have one that didn't make a pistil till day 70 flower.

Oh jeez really ? . All I’m getting is just veg growth and stretch . I’m running out of height soon

I think you just flipped them when one strain wasn't mature enough to flower.

Note that on the first two pictures, the leaves are still coming out mostly opposite each other along the stem, rather than alternating from one side of the stem to the other. In the third pic, that plant has gone to an alternate leaf pattern, meaning it will probably start showing flowers very soon.
